Don't get me wrong, I quite like some HDR shots, and have done some myself. It's just that too many of them have an entirely unnatural, oversaturated overdosed on caffeine look about them, that I for one don't really take to.
I have the same problem with digital compacts which offer a "vivid colour" option: again, the result just looks.... artificial.
Which is not to say that HDR etc don't have a valid artistic role to play, just not an obvious one I submit, in landscape photography,.
